Rarest A-body on Fabo?

I would have to consider the 1966 D-Dart Super Stock one of the most rare. 275 HP-273. Reportedly there were 50 build for homologation, but I have been doing Mopar stuff for over 60 some years and have never seen a real one. The LO23 is a very interesting vehicle if you like early A's. One was sold at auction a few year back and did have the correct VIN. This is a quote from another article. "These cars have a VIN that begins LO23. The order includes the following sales codes: 699 – Special Order (Super Stock Dart); 409 – Special Order Axle; 364 – Super Stock; 624 – heavy-duty suspension; 32 – engine code; 554 – delete rear seat belts; 393 – four speed transmission; 21 – 6.95 X 14 BSW rayon 2-ply tires; 408 -Sure Grip; P4H – trim code (red); WW1 – paint" code (white)." Note gigantic tire selection.
